REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 USC § 119(e) of the U.S.provisional patent application Ser. No. 62/652,503, filed Apr. 4, 2018,and the same is incorporated in its entirety.

BACKGROUND OF THE INVENTION A. Area of the Invention

The invention relates to a composition for providing in an automotivehead gasket fix of a head gasket within a response of a cooling gasket.

B. Prior Art

A number of engine cooling system sealants exist under the trademarksSTEEL SEAL, BLUEDEVIL HEAD GASKET, and BAR's HEAD GASKET REPAIR.

Of the above three different methods of engine cooling sealants, themost generally known is the STEEL SEAL product.

The invention relates to a composition for combustible and the like forparticularly sealing cracks in devices as heating cores, freeze plugs,radiators, cracked or warped head and blown head gaskets. The mostcommon approach generally taken to repair such cracks is to utilizesolid particles act as plugs for scaling the cracks. A difficulty withthis conventional approach is that it is applicable only to large crackswith varying effectiveness but is not effective with respect to verysmall cracks which are too small for the particle to enter. Anotherdisadvantage with such conventional techniques is that such techniquesoperate too slowly.

Cooling system devices that dissipate heat generated by burning of fuelcompulsorily exist in internal combustion engines. All the engines thatuse gas, kerosene, gasoline, and diesel as fuel belong to the internalcombustion engines. For example, the cooling system of an automobileuses coolant solution composed mainly of glycols, and excessiveoverheating of engine by leakage and depletion of coolant by any meanscan shorten durability of the engine and cause metallic cracks on theengine parts.

Cracks, openings, and microscopic holes on a radiator, cylinder block,cylinder head, and cylinder head gasket participating in cooling ofinternal combustion engines, cause waste of unnecessary resources andeconomical defrayment of consumers when no other methods are availablebut replacing the relevant parts as the sole solution.

There have been efforts to repair cracks of internal combustion engineswithout disassembling and replacing damaged devices, and severalproducts are commercialized and marketed. One such representativeexample of using sodium silicate, main ingredient of majority ofcurrently marketed crack repairing products, can be found in U.S. Pat.No. 4,708,195 (1987). Sealing formulation of 95.8% sodium silicate, 4.1%water, 0.16% cupric sulfate pentahydrate, and 0.005% arabic gum has beendisclosed. In another U.S. Pat. No. 4,765,629 (1988) described a sealingsystem composed of a liquid carrier and solid particles, a liquidcarrier composed of water and sodium silicate, and solid particlesselected from silver solder flakes, lead solder flakes and pure groundpepper, and solidifying at 150 degree. F. in the crack.

In still another application, U.S. Pat. No. 4,973,360 (1990) expanded onthe kinds of silicates in addition to sodium or potassium silicatealready in use, and disclosed a sealant solution composed of 25% water,25% ethylene glycol, and 50% aqueous solution composed of compoundsselected from silicates of lithium, ammonium, rubidium, cesium, andgermanium, and oxides of sodium oxide with aluminum oxide, calcium oxideor magnesium oxide. Synthetic polymer polyacrylic acid was firstdescribed in U.S. Pat. No. 6,767,395 (2004). In that application, aliquid aluminum stop-leak formulation using water, polyacrylic acid,cellulose fibers of 0.075-0.3 mm, polyester fiber of 0.3 mm, aluminumparticles of about 320, and other components are disclosed. In U.S. Pat.No. 6,840,990, a sealing composition incorporating sodium nitrate orazoles as corrosion inhibitors is described.

Further prior art of the above type are known as U.S. Pat. No. 6,159,276(2000) to Barks; U.S. Pat. No. 6,324,757 (2001) to Barks; U.S. Appln.Pub. 2008/0087195 (2008) to Yoon; U.S. Pat. No. 6,647,622 (2003) toHipple, et al; U.S. Pat. Pub. No. 2011/0042902 A1 to Herior-Watt Univ.,and U.S. Pat. No. 7,749,560 (2010) to Bell for Blue Magic, Inc.

Such compositions are known by their kinematic viscosity, one of theaspects is its thickening effect thereof.

SUMMARY OF THE INVENTION

A composition or system for sealing warped or cracked head gasket havingtotally one pint (16 fluid ounces) or (480 ml) substantially consistingof:

4.7 fluid ounces (about 140 ml) sodium silicate; 3 fluid ounces (about90 ml) potassium silicate; 2.2 fluid ounces (about 66 ml) propyleneglycol pH 8-10; 4.6 fluid ounces (about 138 ml) of water; 1.0 ounces (30ml) citric acid (2) H₂ C₆ H₅ O; and 0.5-ounce (15 ml) o-hydroxy phenyltriazanes. The propylene glycol may be toxic. Also, one may also include0.5 ounce of green dye (triarylmethane).

The present sealant is a system for repairing an engine of a sealingsystem for a combustible engine.

In accordance with one embodiment of this invention, the sealing systemincludes a liquid carrier for solid particles. Unlike the conventionalsystems, however, the liquid carrier itself is capable of coagulationand solidification. Thus, the invention utilizes the advantages of theprior techniques by initially closing large cracks and openings with thesolid particles and utilizing the liquid to fill the tiny cracks and tocomplete the filling of the large cracks upon solidification of theliquid.

In another embodiment of this invention, the sealant may use a mixtureof sodium silicate, potassium silicate, a glycol, and particulates, withoptional coloring agents and preservatives.

An object of the invention is to provide an improved sealing systemwhich has the advantages but not the drawbacks of the above system.

A further object of this invention is to provide such a sealing systemwhich provides sufficient strength and durability to effectivelywithstand pressure that might be applied.

A still further object of this invention is to provide such a systemwhich is characterized by its quickness in sealing cracks regardless ofthe size of the cracks.

The above and yet other objects of the present invention will becomeapparent from the hereinafter set forth in the Detailed Description ofthe Invention, and Claims appended herewith.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides a composition for sealing holes or cracksin engine cooling systems effectively and for sealing warped engineheads. The invention provides a method and liquid composition which maybe solidified to seal cracks, holes, and warped areas. The solidparticles function as bonding agents to which the liquid becomesattached while solidifying. The solidification of the carrier takesplace such that a reactant or catalyst is added to the liquid carrierimmediately after time of insertion, thereby causing a chemical reactionto form solidification. In the preferred form of the present invention,solidification takes place as a result of heat applied to the liquidcarrier.

By utilizing heat to cause solidification, the invention particularly isuseful for sealing cracks or holes in a combustion engine in its coolingsystem. For example, the invention is utilized for sealing cracked orwarped heads or blown head gaskets in an engine or for sealing heatingcores, freeze plugs, radiators or otherwise in the cooling system. Inone aspect, the engine or cooling system is a gasoline or diesel typesuch as those used in vehicles such as cars, trucks, and boats.

In the present invention, a liquid part of sealant is obtained by mixingsodium silicate and potassium silicate in liquid form, to which is addeda glycol and water. In one aspect, the liquid contains various coloringagents and preservatives. In some applications, the liquid containsparticulates such as pumice or corrosion-resistant metal filings.

The silicates of the present composition include potassium silicate andsodium silicate. The silicates are high grade silicates and may be mixedin specific proportions. For example, sodium silicate may be present in30% volume based on the total amount of the silicates, more preferably30-60% volume. Thus, the total amount of silicates comprises about30%-60% volume of the aqueous silicate mixture.

Sodium silicate or water glass may be pure sodium metasilicate ormixtures of sodium metasilicate with two other silicates. It isavailable as granular, crystals, or 40% Baume solution. The N Gradeliquid is preferred.

Sodium silicate is a term applied to a group of materials. They arecompositions in which sodium oxide is combined with various amounts ofsilica, usually with some water. They differ in SiO₂/Na₂ O ratio and inthe amount of water attached. Sodium silicates are available in SiO₂/Na₂O from 0.5 to 4. The number of water molecules per one molecule ofsodium silicate varies from 0 to 10.5.

The silicate mixture of the present invention is provided in liquidform. The potassium silicate of the present invention may be K₂ SiO₃, K₂SiO₅, and/or K₂ Si₄ O₉. Preferably, the potassium silicate is present inliquid form, such as solubilized in water, based on the total amount ofsilicates, more preferably, 30-60% based on the total amount ofsilicates. The balance being comprised of sodium silicate.

The composition also contains a glycol in water. Suitable glycols foruse in the invention include diethylene glycol, ethylene glycol,propylene glycol, dipropylene glycol, polyglycols, glycol ethers, andmixtures of diethylene glycol, ethylene glycol, propylene glycol,dipropylene glycol, polyglycols, and glycol ethers. In one aspect,diethylene glycol is preferred. Glycols provide a composition with a lowfreezing point and lubrication for the water pump. A compositioncontaining about 12-15 vol. % glycol, for example, is used in climateswith temperatures down to about −10 degree. F. (about −23. degree. C.).In a preferred embodiment of the invention, the glycol componentcomprises 1-25 vol. % of the composition. More preferably, thediethylene glycol and water comprise 10%-20% of the total composition.Most preferably, the diethylene glycol and water comprise 20%-35% volumeof the total composition. The diethylene glycol is particularlyadvantageous since this additive allows for a cooler running system andhelps the thickening effect of the sealant.

In Composition I of the inventive composition of 16 fluid ounces orabout 480 ml includes about:

4.6 fluid ounces (138 ml) of water (about 28%).

4.7 fluid ounces (about 140 ml) sodium silicate (about 29%).

3 fluid ounces (about 90 ml) potassium silicate (about 18%).

2.2 fluid ounces (66 ml) toxic propylene glycol at pH 8 to 10 (about14%).

1.0 ounce citric acid (30 ml) (2) H₂ C₆ H₅ O (7.5%).

0.5-ounce (15 ml) o-hydroxy phenyl triazanes (3.75%).

Also, toxic propylene glycol as substantially the same as Prestonelow-toxic, but operates as a coagulative or swelling basis, i.e., athick-like sealant used in head gasket failures, i.e., under 10durometers.

One must note that head gasket failure is a symptom, not a cause ofoverheating. The original source of cooling system failure, if stillpresent, must be repaired before attempting to repair your head gasket.

In composition II, for sealing, warped or cracked head gasket coolantconsisting essentially of:

-   -   (a) 25% to 30% of water;    -   (b) 26% to 32% by ml of sodium silicate;    -   (c) 15% to 21% by ml of potassium silicate;    -   (d) 12% to 16% by ml of propylene glycol by pH 8-10, said glycol        is selected from the group consisting of diethylene glycol,        ethylene glycol, propylene glycol, dipropylene glycol,        polyglycols, glycol ethers, and mixtures thereof;    -   (e) 5% to 10% by ml of citric acid (H₂, C₆, H₅ 0); and    -   (f) 2.5% to 5% by ml of 0-hydroxy phenyl triazanes.

The formulation as recited above, in which includes a coagulant includesbenzoates, molybdates, alkali metal borates, sodium silicates, potassiumsilicates, triazoles, acids, boric salts, sodium hydroxides, potassiumor hydroxides, or lithium hydroxides.

The formulation also recited further may include about 0.5 ounces ofgreen dye (triarylmethane).

An example thereof such as a thick-like sealant include an aqueous mediacomprise a triazole, a benzoate or a silica from 0.1-0.3 weight percentof a hydrocarbyl triazole, preferably benzotriazole or tolyltriazole.Additionally, such corrosion inhibitors which may optionally be employedin admixture with the corrosion-inhibited antifreeze concentrate oraqueous antifreeze formulation of the instant invention are alkali metalhydroxides silicates, nitrates, benzoates, and molybdates, orcombinations thereof, in a concentration rate of 0.1-5.0 weight percent.

Aqueous non-phosphate corrosion inhibited antifreeze formulations of theinstant invention are those where the antifreeze concentrate of theinstant invention is diluted with 10-30 volume %, or preferably 20-40volume % of water. The antifreeze concentrate and aqueous antifreezecomposition of the instant invention exbibit a synergistic resistance tocorrosion for a variety of metals in comparison with compositionscontaining either the monobasic acid or salt or alkali metal boratecomponents described above.

Problems such as Steel Seal of Warwickshire, UK is not compatible withall antifreeze formulations. Therefore, for best results, coolant shouldbe temporarily drained and replaced with fresh water. Once repaired,drain such as Steel Seal from the cooling system and replace with 50/50antifreeze.

Water in Oil

Repair Guidelines

Recommended Dose:

4 cylinder engine—1 Bottle (4 Cylinder Kit)

6 cylinder engine—2 bottles (6-8 Cylinder Kit)

8 cylinder engine—2 bottles (6-8 Cylinder Kit)

Blown Head Gasket Repair in Three Steps:

1. Make sure engine is cold and remove the radiator cap. The formulationseal directly into the radiator. Replace radiator cap and tighten.

2. If vehicle is roadworthy: Start engine and drive at freeway speeds of5 miles, maintaining between 3,000-4,000 rpm, then shut off engine. Ifvehicle is not roadworthy: Turn heater and fan to maximum. Start engine,run to operating temperature and then run on high idle (1,000-1,500 rpm)for 30 minutes.

3. Turn off vehicle and allow to cool completely. Top up withantifreeze/water as necessary, replace radiator cap tightly.

For Best Results:

If you have tried inferior products, flush you cooling system with cleanwater after disconnecting bottom radiator hose. Do not use a flushingagent.

If you have flushed system, reconnect bottom radiator hose.

Additional for The Directions:

These directions are for people that have a lot of back pressurebuilding up in the cooling system, usually shown as bubbling in theheader tank or air forcing past the coolant cap.

Locate the cylinder causing the bubbling in the overflow tank orbackpressure. Remove plugs at a time until bubbling stops.

Before starting the engine, remove the spark plug or injector from thecylinder that was causing the bubbling in the overflow tank or backpressure. If accessible, remove injector wire from that cylinder. Thiswill limit the amount of unburned fuel going into the combustionchamber.

If you cannot find the spark plug that is missing, run the engine withthe coolant level down to the top of the radiator core and with theradiator cap off or leave the expansion cap off the expansion bottlewith water only just visible. Make sure to run the engine up totemperature with the spark plug/Injector out and from the one final timewith the spark plug/injector back in place. However, if a vehicle isroadworthy, then start the engine and drive at freeway speed of fivemiles, maintaining between 3,000-4,000 rpm, and then shut off engine.

For One Area above for “The Formulation”

Prestone Low/Toxic—(propylene glycol pH 8-11)

Biodegradable/non-toxic antifreeze or available at O'Reilly Auto.

Prestone conventional green antifreeze—(Ethylene Glycol-pH 8-11) Lowsolvent effect, silicate stabilizers and high pH provide the bestprotection.

The invention is also characterized by a seal having excellent strengthand integrity sufficient to withstand the normal pressure to which itwould be subjected. A particularly great advantage is the quickness orspeed in which the sealing action takes place. A further advantage isthe ability of such sealant to penetrate tiny cracks and thereby preventsuch cracks from getting larger.

In general, the invention applies to sealing any type of cracks whereinliquid may flow into the cracks. As noted above, such cracks would thenbe effectively sealed in a rapid period of time. The cracks may be incombustible engine cooling systems or may be in other devices such ashome or building heating systems.

An advantage of this variation is that it permits the sealing of cracksor leaks at lower temperatures than with the first embodiment.Additionally, the particular mixture of components which includesethylene glycol permits the provision of anti-freeze which is ordinarilyalready in the engine to function as a source of the ethylene glycol.

The invention in its various embodiments thus provides a sealant whichis particularly effective for cracks and leaks at various ranges oftemperatures.

It will thus be seen that the objects set forth above, among those madeapparent from the preceding description, are efficiently attained and,since certain changes may be made in carrying out the above method andin the article set forth without departing from the spirit and scope ofthe invention, it is intended that all matter contained in the abovedescription and shown in the accompanying drawings shall be interpretedas illustrative and not in a limiting sense.
